Five researchers from the University of Sri Jayewardenepura, Prof. Meththika Vithanage, Dr. Anushka U, Rajapaksha, Prof. Neelika Malavige , Dr. Dhanushka Udayanga and Dr. K. K. Asanka Sanjeewa are ranked among World’s Top 2% Scientists in the 2021 List of outstanding researchers prepared by Elsevier BV, Stanford University, USA. This is the newest data-update for “Updated science-wide author databases of standardized citation indicators” published on October 10, 2022. Only 3 USJ scientists were in this list for year 2020, and for year 2201 USJ scientist number has increased to 5. Prof. Meththika Vithanage, Dr. Anushka U, Rajapaksha, and Prof. Neelika Malavige made it again to this year 2021 list from 2020 list.
In this career-long database and single year dataset, considered 195,605 scientists and 200,409 scientists respectively from 22 scientific fields and 176 subfields. The Top 2% is based on the academics’ scientific achievements measured by the bibliometric index. The evaluation criteria include the H-index, the impact factor, total citations, co-authorship adjusted hm-index, citations to papers in different authorship positions and a composite indicator and many more.
There are 38 Sri Lankan (up 14 from year 2020) scientists ranked in this World’s Top 2% Scientists list from various institutes: University of Sri Jayewardenepura, International Water Management Institute, National Institute of Fundamental Studies, Munasinghe Institute for Development, University of Peradeniya, University of Moratuwa, Wayamba University of Sri Lanka, University of Colombo, University of Kelaniya, Uva Welassa University, Rajarata University and the University of Jaffna. Out of 38 Sri Lankan scientists, 5 of them are from the USJ, Prof. Meththika Vithanage, Dr. Anushka U, Rajapaksha, Prof. Neelika Malavige , Dr. Dhanushka Udayanga and Dr. K. K. Asanka Sanjeewa.
The use of citation metrics has become widespread, but challenges relate to what citations and related metrics fundamentally mean and how they can be interpreted or misinterpreted as a measure of impact or excellence. Many other problems are of a technical nature and reflect a lack of standardization and accuracy on various fronts. Since there is no large-scale database that systematically ranks all the most-cited scientists in each and every scientific field to a sufficient ranking depth. Moreover, self-citations are not excluded from the existing rankings. However, as with all other ranking systems, there can be negatives in this particular ranking system, though it has been recognized throughout the world.
